DNV has introduced new class rules for electrical shore connections specifically tailored for tankers, contributing to setting sector norms.
The need for new rules on shore power for tankers emerged following amendments to the California Air Resources Board’s (CARB) Ocean-Going Vessels At-Berth Regulation, requiring tankers to have emission control strategies in place at specific ports from January 2025.
As a response to these regulatory changes, DNV, on behalf of the Western States Petroleum Association, conducted a comprehensive assessment of the feasibility of meeting the new requirements.
Why shore power?
- Causes significant reduction of air emissions (SOx, NOx, PM) and improves port’s microclimate
- Reduction of greenhouse gases when used in combination with Renewable Energy Sources
- Raise in oil price has led shipowners seek alternative power sources
- Elimination of noise and vibration improves working conditions for seafarers
- Enabling maintenance of auxiliary engines while idle, extension of life of auxiliary gens and reduction of maintenance costs
The assessment found significant gaps in the existing regulatory framework for shore power on tankers, emphasizing the necessity for more robust rules. The gaps included:
- lack of standardization for connection points
- limited interface compatibility with terminal systems
- technology development constraints.
The project also identified a need for risk evaluation in handling hazardous cargo during implementation of shore power technology.
These gaps underscore the importance of establishing industry-standard guidelines to address safety concerns effectively and ensure the well-being of personnel and assets involved in tanker operations.

To ensure a comprehensive and inclusive process, DNV sought feedback from interested parties through proposals for a hearing starting 8 March. After incorporating insights and expertise from leading energy charterers, tanker terminals, and prominent ship owners, DNV has finalised the rules after a five-week review period.
We appreciate their and all our industry partners’ efforts as we strive to accelerate the adoption of innovative solutions to reduce emissions
